    Description

    NOS original fuel pump Diaphram  spring for the WWII AC fuel pump.  These NOS springs were salvaged from original fuel pump kits that were broken up for parts.  Many new production fuel pumps have a very stiff spring that increases the fuel pump pressure over 4 lbs and over powers the needle valve in the carburetor.  If you have high fuel pump pressure, this NOS spring will probably fix the problem.
